Okay - I know there are plenty of threads about doing home PCB creation - I know how to do this, and I'm probably going to end up doing it, but I just don't understand something.

How on EARTH do commercial entities get REASONABLY priced PCBs? Is the only option for this in-house production? Everywhere I've looked wants at least $50 for a single sided, very simple 3x5 PCB. Is it just NOT POSSIBLE for a company to price an electronic device with a 3x5 PCB in a quantity of about 100 pcs under $100?

I make my single-sided PCBs at home. They cost me much less than commercial boards and a typical board takes me about 30 minutes, excluding drilling.

www.olimex.com does single sided 6x4" boards (actually 160x100mm) at $26. (You can place several smaller designs on such a board and they will cut it up into the individual pieces for you, aka. de-panelizing.) Double-sided boards, same size, is $33. Certain limitations apply (max 500 drill holes, a limited set of drill sizes etc). Breaking them will add a few $ to the price. See web-site for details.

I have not used them myself (yet) but several 'freaks have, and I have only heard good reviews.

And this is in single quantity. I would expect that for larger quantities the price per board will be lower as there is an embedded setup fee/cost in that price. I wouldn't be surprised if the cost for eg. 1000 such boards would drop below $10. You'd have to ask for a quote to for the definitive answer, though.

I am fairly certain that there has been other board-houses discussed here that offers similar pricing.

Leon needs just half an hour, I need a bit more. But for sure it's fun, and you can make them during the weekend f.i.

Johan's suggestion is a good one too, in case you like professional PCB's

I have good results with http://www.makepcb.com/ If you add your domicile in your profile, you will get better answers: Freaks are all over the world

If you want to see pricing for larger quantities check out www.pcbcart.com

As you can see the price/PCB falls off rapidly.

Edit: Get experimenting and make a couple of PCB's at home.. it is really not so hard and can be quite fun too. Double sided takes just a little more effort but is in no way impossible.

Don't forget www.batchpcb.com for small runs of boards. They charge a $10 setup fee and $2.50 per square inch.

You are up against the basic issues of scale. 100 boards is pretty small for most board houses. They would much rather work in the 1000's or more. So, their small-order pricing is not very attractive. Those that DO small orders tend to have upper limits where they are no longer attractive. PCBExpress is one that seems to transition from small scale to large relatively well. They get about $60 for two 2"x3" boards and the price (per board) drops rapidly from there. Once you get to 100's, it shifts to their standard fab process. But batchpcb that Tom mentioned is a lot better than that.

It just takes searching and asking (like you have) and you will turn up better choices than the one you mentioned.

PS: One major difference between BatchPCB and PCBExpress is on-shore vs off. BatchPCB takes you 10 to 19 days. The PCBExpress gets you boards in about 5 days. You want fast, so pay more. I am not promoting PCBExpress, just pointing out some of the issues that need to be considered.

Another issue is proprietary file formats, such as ExpressPCB. Once you have used their software, you are stuck with them or a relay-out. J.

Thank you for the replies, fellow freaks...

Guess it looks like I'll PROBABLY be doing a lot of in-house work with some muriatic acid and my laser printer. :mrgreen:

As for the etching, I like ammonium persulfate but if you want an interesting alternative google "CuCl etching".

Why not just do a dual layer board? The flexibility of having 2 layers to work with is immense, with dual layer you should not ever have to put jumper wire and everything looks much cleaner.

If you are in USA then the best place I have found is pcbfabexpress.com. Use one of their specials such as $10 per board for 2 layers with free solder mask and free stencil. The board is very high quality, they are very fast and customer service is very good. Just make sure that your board is within the specs of the special or else you pay through the nose in extra fees. Shipping is really expensive if you live outside the USA so that is why I would consider this a good deal for those in the USA.

My current fav is myropcb.com, good quality board, great service. For less than 5-10 units then they are not competitive but for more than 10 boards they become pretty competitive. For higher volume, ~50 or more, their prices are the cheapest around.

Yeah, that's exactly what I'll be using.

To get started, you just need hydrochloric (muriatic) acid and some 3% H2O2 (drug-store grade hydrogen peroxide).
